(x% * 4) + 4 = 4.32
Solve for 'x':
4x + 4 = 4.32
Subtract 4 to both sides:
4x = 0.32
Divide 4 to both sides:
x = 0.08
Multiply by 100:
0.08 * 100 = 8%
An easier way to do this is to find the percent increase.
First, subtract the two numbers.
4.32 - 4.00 = 0.32
Divide this to the original amount:
0.32 / 4.00 = 0.08
Multiply by 100:
0.08 * 100 = 8%
We basically did all the steps from our equation above.
